Advantages and disadvantages of bipolar junction transistor (BJT)

There are some advantages of bipolar junction transistor (BJT) are as given below,

1. The bipolar junction transistor (BJT) has a large gain bandwidth.
2. The BJT shows better performance at high frequency.
3. The BJT has a better voltage gain.
4. The BJT can be operated in low or high power applications.
5. The BJT has high current density.
6. There is low forward voltage drop.

There are some disadvantages of bipolar junction transistor (BJT) are as given below,

1. The bipolar junction transistor (BJT) more noise produced.
2. The BJT are more effect by radiation.
3. BJT has a low thermal stability.
4. The switching frequency of BJT is low.
5. It has a very complex base control. So it may lead to confusion and requires a skilful handling.
